All right, let's get real esoteric, here. My friend Luke Faust was in a short-lived band called Insect Trust headed by Robert Plamer, who became a well known music critic and author. They did some great stuff, but didn't stick together very long... had just about no commerical success. That's about the only folk-rock band I can remember that actually had some tracks with clawhammer banjo lead.. had a great female lead singer. Female lead singer for the Youngbloods? The three albums I had didn't have a female lead singer. Jesse Colin Young sang most of the leads.
Yeah, I go back a ways. I was at the original Woodstock, and still have my tickets to prove it. They go for big bucks now... probably could auction it off on eBay.
